Estimating Turning Movements at Roundabouts Using Bluetooth Technology

Turning movement counts at Roundabouts have historically been difficult to acquire. With the advent of Bluetooth wireless communication devices becoming commonplace for individuals to own and possesses while operating a vehicle, an opportunity was created to investigate the feasibility of applying this technology to turning movement counts at roundabouts. Two different locations were studied in Kansas, a rural five-leg, and an urban four leg roundabout were chosen. Bluetooth data loggers were deployed upstream of the central island at each location from which origin-to-destination leg data could be captured. When turning movement percentage data was compared to ground truthed human observations and statistically compared, the rural location was not statistically different, and the urban location barely was statistically different.
